0x80000018 0x008F6C 0 We found that the attached-bit before the LSP generated by R2 is gone,ccna practice exam online free, but the Overload-bit is set . Now let's go look at the routing table. R3 configuration is as follows Path Protect Parameters: O My Address: 10.1.12.1 Global Pool Sub Pool Configuration example 1 : *Aug 18 09:06:02.699: Flags: (0x7) Local Prot desired, Label Recording, SE Style !! Flags are reflected in the flag 104 The forwarding of IP packets in each hop router is based only on the destination address. Link connected to: a Transit Network 301 *Aug 18 09:06:07.919: Remote binding: tsr: 2.2.2.2:0, tag: imp-null In the isis process mode, if the redistribute command directly hits the level parameter, the default is to re-publish to level-2. Note: a FEC can contain multiple streams, but not a stream of a FEC , such as looking at a host Sina website, which is a stream and looking at Sina's video, which in turn is a stream, the two streams When Sina sends to a remote host, the path should be the same, so one FEC has multiple streams, but each stream does not belong to a separate FEC. The area address groups configured on the router are listed. It only appears in non-pseudo nodes Above we can see the reservable bandwidth of all tunnel priorities. Now let's modify the reservable bandwidth of the tunnel with priority 6 . Tunnel mpls traffic-eng autoroute announce Router ospf 1 3 area addresses. The latest IOS version can be set to 255. If the maximum number of area addresses supported by the two routers is inconsistent, that is, the MAX.Areas field does not match, the IIH message is ignored . R3#show ip route Path: valid 75M !! Pay close attention to here Packets with the same processing mode according to the process or IP DSCP field Ip address 5.5.5.5 255.255.255.255 The configuration of ip rsvp bandwidth R3 is as follows: When we select a DIS , DIS represents the broadcast network, including all ISs connected to the broadcast network. Src 1.1.1.1, Dst 4.4.4.4, Tun_Id 0, Tun_Instance 2 RSVP Path Info: 3 area addresses. The latest IOS version can be set to 255. If the maximum number of area addresses supported by the two routers is inconsistent, that is, the MAX.Areas field does not match, the IIH message is ignored . Frame-relay map ip 10.1.123.3 301 broadcast frame-relay map clns 301 broadcast Redistribute isis ip level-2 into level-1 route-map test Ip address 10.1.24.4 255.255.255.0 Tunnel mpls traffic-eng bandwidth 33000 TOS 0 Metrics: 10 Interface fas0/0 Interface eth 0/2 MOSPF extension provides support for IP multicast routing Record Route: NONE Then you need the top-level tag, which looks at the next hop. The next hop is 5.5.5.5 , so be sure to find the 5.5.5.5 tag. As we have seen from the routing table, at this point R2 goes to 5.5.5.5 and actually enters the TE tunnel , then: Unmarked / No Label: The entire label stack is removed and the message is forwarded in an unlabeled manner. Local Outgoing Prefix Bytes Label Outgoing Next Hop Label Label or Tunnel Id Switched interface Et0/1 Used to publish a complete link state database on a router , CSNP is used to inform other routers of their own database may be outdated or lost LSP . 10.1.23.3 Mpls ip Time since created: 11 minutes, 42 seconds Time since path change: 10 seconds Number of LSP IDs (Tun_Instances) used: 9 R1(config)#interface fa0/0 ! 10.1.12.2 Interface eth 0/0 Mpls ldp router-id loopback0 mpls label range 300 399 interface fast0/0 Retention mode (the Label Retention) : free mode (Liberal Retention) It should be noted here that if a label package is received and the label is 0 , the label will be directly popped up and the data will be submitted to the FIB for searching, and there will be no loss of the search. Label tag with tag 0 , why not just remove the tag (allocate a 13 value to the next hop to let the next hop remove the tag), why keep the tag header with 0 ? This is to maintain the uniformity of network planning under certain circumstances. For example , if QoS of MPLS is deployed , the EXP field in the label package is required, and then a label is required. When QoS is implemented , the last hop must carry the exp bit. Therefore, the label cannot be ejected. You need to configure mpls ldp explicit-null. The label assigned to a specific route is 0 and passed to the LDP neighbor (such as the penultimate hop). .
